Catheter with an aorta-occluding balloon
First Claim
1. A catheter with an aorta-occluding balloon, the balloon having an inner surface and an outer surface, the catheter comprising:
- a main lumen formed with a proximal end and an L-shaped distal end;
the main lumen extending between the ends so as to bring the ends into fluid communication with one another;
the balloon being secured to and around the distal end;
a first subordinate lumen extending along the main lumen and opening into the balloon;
a connector disposed adjacent to the proximal end so as to receive a balloon-expanding means for expanding said balloon, with the first subordinate lumen being in fluid communication with the connector;
a second subordinate lumen also extending along the main lumen and having an end open outwardly of the catheter adjacent to the L-shaped distal end and opposite to the balloon;
a further connector also disposed adjacent to the proximal end so as to receive a solution-feeding means, with the second subordinate lumen being in fluid communication with the further connector, said catheter being insertable into an aorta, said balloon-expanding means expanding said balloon so as to place said outer surface in contact with the aorta, said outer surface extending substantially parallel with the L-shaped distal end.

Abstract
A catheter with an aorta-occluding balloon comprises a tube 1 extending between its L-shaped distal end 8 and its proximal end 9, and having a main lumen 2 formed centrally of the tube, a first and second subordinate lumens 3 and 4, both of them extending longitudinally through the tube'"'"'s periphery, and a balloon 5 secured to and around the tube'"'"'s distal end 8. The first lumen 3 has at its end near the proximal end 9 a connector 6 for receiving a balloon-expanding means, and the second lumen 4 also has at its end near the proximal end 9 a further connector 7 for receiving a solution-feeding means. The catheter is thus designed to occlude a calcified blood vessel so that its intima may not be injured, and a fluid such as a protective solution can be supplied to the cardiac muscle through the coronary artery.
